Description

Protein heterodimers and uses thereof

Background

Although immune responses to tumor antigens can be detected (Disis et al (1997) J.Clin.Oncol.15:3363-3367), malignant cells causing disease are generally unable to elicit an immune response that leads to rejection. Studies have shown that the immunogenicity of tumor cells can be enhanced by introducing immune modulatory molecules (such as cytokines and co-stimulatory molecules) into the cells. However, eradication of residual cancer cells may require targeting of widely disseminated micrometastatic tumor deposits that are not directly amenable to gene transfer. Furthermore, the expression and stability of the introduced immunomodulating molecules is often far from satisfactory. Immune modulators (such as cytokines) produced by cells of the immune system may directly or indirectly activate cells of the adaptive immune response and play an important role in eliciting protective anti-tumor immunity. The innate immune system can be triggered by bacterial products or "danger" signals that lead to the release of proinflammatory cytokines such as IFN-alpha, TNF-alpha and interleukins.

Several studies have shown that immunomodulators can exert antitumor effects in animal models and cancer patients. However, the short half-life and systemic toxicity associated with the use of immunomodulators greatly limits their use. In CN200880117225.8, a chimeric construct comprising interferon linked to the c-terminus of an antibody targeting a tumor associated antigen has been described. However, fusion proteins expressed from such chimeric constructs are often very unstable in vivo and their expression yields are often insufficient for industrial scale production.

Recently, heterodimeric proteins (such as bispecific antibodies) have been developed to allow co-engagement of two different targets. Traditionally, bispecific antibodies are produced by fusing two cell lines, each producing a single monoclonal antibody (mAb). However, in such processes, the amount of bispecific antibody (or heterodimeric protein) is low and extensive purification is required to isolate the desired product.

In the 1990's, Carter et al developed a "knob-and-hole" model that improved bispecific antibody production by introducing asymmetric modifications in the CH3 region of two monospecific initiator proteins (Ridgway, Presta et al, 1996; Carter et al, 2001). However, even with "nodal pore" modifications, protein homodimer formation cannot be controlled or eliminated very effectively, and yields of heterodimeric proteins are difficult to further increase.

Disclosure of Invention

Thus, there is a great need for targeted expression of immunomodulators which can be produced in relatively high yields on an industrial scale and have a relatively long half-life in vivo for use in the treatment of conditions or diseases associated with hyperproliferation of cells and/or tissues (e.g., various neoplasms, different types of cancer and/or tumors). Furthermore, the yield of such products should be high enough to avoid complicated purification processes and/or to reduce the risks associated with undesired impurities.

The present application satisfies this need and provides related advantages as well. The present application includes protein heterodimers useful for inhibiting tumor growth, as well as compositions, medicaments, and/or kits comprising the protein heterodimers. In addition, the present application provides protein mixtures comprising the protein heterodimers and having few, if any, undesired impurities, such as undesired protein homodimers. The present application also provides methods of producing protein heterodimers or protein mixtures, and pharmaceutical uses of protein heterodimers and/or protein mixtures in inhibiting tumor growth, including but not limited to the treatment of cancer.

In some aspects, the protein heterodimers of the present application have significant anti-tumor activity. In some aspects, the protein heterodimers of the present application have high expression yields. In some aspects, the protein heterodimers of the present application have a long half-life in vivo. In some aspects, the protein heterodimers of the present application are particularly suitable for large-scale industrial production. In some aspects, the protein mixtures of the present application comprising the protein heterodimers contain little or substantially no undesirable impurities.

In one aspect, the present application provides protein heterodimers. The protein heterodimer may comprise a first member and a second member different from the first member, the first member may comprise a light chain and a heavy chain comprising a first Fc region, the light chain may complex with the heavy chain to form a targeting moiety that exhibits binding specificity for a tumor antigen; the second member may comprise a polypeptide comprising an immunomodulator fused to the second Fc region; the first member can associate with the second member through complexation of the first Fc region with the second Fc region to form a heterodimer; and the first Fc region may comprise a first modification and/or the second Fc region may comprise a second modification, wherein the first modification and/or the second modification may promote heterodimerization between the first member and the second member more effectively than a nodal-pore modification comprising a nodal modification and a pore modification. For nodal-pore modifications comprising a nodal modification and a pore modification, the first Fc region may comprise a nodal modification and the second Fc region may comprise a pore modification. Alternatively, the first Fc region may comprise a pore modification and the second Fc region may comprise a knob modification.

Detailed Description

Before describing embodiments of the present application, it is to be understood that such embodiments are provided by way of example only and that various alternatives to the embodiments of the present application described herein may be employed in practicing the present application. Numerous variations, changes, and substitutions will occur to those skilled in the art without departing from the application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present application, suitable methods and materials are described below. In case of conflict, the patent specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and not intended to be limiting. Numerous variations, changes, and substitutions will occur to those skilled in the art without departing from the application.

As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

As used herein, the term "proteinaceous" generally refers to a substance or molecule that is related to, similar to, or is a polypeptide or protein. For example, a protein heterodimer of the present application can be a heterodimeric protein, or a heterodimer comprising two or more polypeptides.

As used herein, the term "heterodimer" generally refers to a molecule (e.g., a protein molecule) that is composed of two distinct members. The two members of the heterodimer may differ in structure, function, activity, and/or composition. For example, two different members may comprise polypeptides that differ in the order, number or type of amino acid residues that form the polypeptides. Each of the two different members of the heterodimer can independently comprise one, two, or more units, polypeptide chains, or portions.

As used herein, the term "targeting moiety" generally refers to a molecule, complex, or aggregate that specifically, selectively, or preferentially binds to a target molecule, cell, particle, tissue, or aggregate. For example, the targeting moiety can be an antibody, antigen-binding antibody fragment, bispecific antibody, or other antibody-based molecule or compound. Other examples of targeting moieties may include, but are not limited to, aptamers, avimers, receptor binding ligands, nucleic acids, biotin-avidin binding pairs, binding peptides or proteins, and the like. The terms "targeting moiety" and "binding moiety" are used interchangeably herein.

As used herein, the term "tumor antigen" generally refers to an antigenic substance produced in or by a tumor cell that may have the ability to trigger an immune response in a host. For example, a tumor antigen can be a protein, polypeptide, peptide, or fragment thereof that forms part of a tumor cell and is capable of inducing tumor-specific cytotoxic T lymphocytes. The tumor antigen peptide may be a peptide produced as a result of degradation of a tumor antigen in a tumor cell, and may induce or activate tumor-specific cytotoxic T lymphocytes upon expression on the cell surface by binding to HLA molecules. In some embodiments, the term "tumor antigen" may also refer to a biomolecule (e.g., protein, carbohydrate, glycoprotein, etc.) specifically or preferentially or differentially expressed and/or found in association with a cancer cell on the cancer cell, thereby providing a preferential or specific target for the cancer. For example, preferential expression may be preferential expression compared to any other cell in the organism, or may be preferential expression within a particular region of the organism (e.g., within a particular organ or tissue).

The terms "tumor antigen epitope" and "tumor antigen determinant" are used interchangeably herein and generally refer to the site of an amino acid sequence present in a tumor antigen that can induce tumor-specific cytotoxic T lymphocytes.

The terms "immunomodulator" and "immunomodulator" are used interchangeably herein and generally refer to a substance that affects the function of the immune system. Immune modulators may enhance or reduce immune responses. For example, the immunomodulator may be an active agent of immunotherapy, including, but not limited to, cytokines such as from bacteria, chemokines, interleukins, cytosine phosphate-guanosine (CpG) oligodeoxynucleotides and dextrans, granulocyte colony stimulating factor (G-CSF), interferons, imiquimod, recombinant, synthetic and/or natural preparations of cell membrane fractions. In some examples, the immunomodulatory agent is a cytokine. In certain instances, the immunomodulator is not an antibody or antigen-binding fragment thereof. In some cases, the immunomodulator is not an immunoglobulin molecule or a fragment thereof (e.g., an antigen-binding fragment).

In some embodiments, the immunomodulator is selected from the group consisting of an interferon, an interleukin, a chemokine, a lymphokine, and a tumor necrosis factor. For example, the immunomodulator may be selected from interferon alpha, interferon lambda, interferon beta, interleukin 10, interleukin 2 and hyperimmune 2.

The term "expression yield" as used herein in the context of protein heterodimers generally refers to the amount of protein heterodimers produced in a functional form upon expression, e.g., when expressed by a host cell.

As used herein, the term "dimeric sequence" generally refers to an amino acid sequence that is capable of forming a dimer or undergoing dimerization. In some embodiments, the dimer is a heterodimer formed from two different members. In some cases, two different members of a heterodimer may comprise different dimerization sequences.

As used herein, the term "heterodimerization" generally refers to the process of forming a heterodimer between two different members (e.g., two different polypeptides), with or without the formation of covalent bonds between the two or more members, e.g., by complexation, association, or aggregation.

As used herein, the term "covalent bond" generally refers to a chemical bond formed between atoms through electron sharing. For example, the covalent bond may be polar or non-polar. In some embodiments, the covalent bond is a disulfide bond.

As used herein, the term "non-covalent pairwise affinity" generally refers to a dimerization or heterodimerization sequence capable of binding to each other through non-covalent interactions, such as via ion-pairs, hydrogen bonds, dipole-dipole interactions, charge transfer interactions, pi-pi interactions, cation-pi electron interactions, van der waals interactions and dispersive interactions, hydrophobic (lipophilic) interactions, complex formation (e.g., complex formation of transition metal cations), or combinations of these interactions.

As used herein, the term "linker" generally refers to a synthetic amino acid sequence that links (connect) or (link) two polypeptide sequences, e.g., two polypeptide domains. The linker may link the two amino acid sequences by a peptide bond. In some embodiments, the linker of the present application links the biologically active moiety to the second moiety in a linear sequence.

The terms "polypeptide," "peptide," and "protein" are used interchangeably herein to refer to a polymer of amino acids of any length. The polymer may be linear or branched, it may comprise modified amino acids, and it may be interrupted by non-amino acids. The term also encompasses amino acid polymers that have been modified, for example, by disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation, such as conjugation with a labeling component. The term is applicable to amino acid polymers in which one or more amino acid residues is an artificial chemical analogue of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers. The term may also include variants on conventional peptide bonds that join the amino acids that make up the polypeptide. For example, "peptides", "polypeptides" and "proteins" may be chains of amino acids, the alpha carbons of which are linked by peptide bonds. Thus, the terminal amino acid at one end of the chain (amino terminus) may have a free amino group, while the terminal amino acid at the other end of the chain (carboxy terminus) may have a free carboxy group. As used herein, the term "amino terminus" (abbreviated N-terminus) generally refers to the free alpha-amino group on an amino acid at the amino terminus of a peptide or the alpha-amino group (imino group when participating in the alpha terminus) of an amino acid at any other position within a peptide. Similarly, the term "carboxy terminus" generally refers to a free carboxy group on the carboxy terminus of a peptide or a carboxy group of an amino acid at any other position within a peptide. Peptides can also include essentially any polyamino acid, including but not limited to peptidomimetics, such as amino acids linked by ether rather than amide linkages.

As used herein, the term "amino acid" generally refers to natural and/or unnatural or synthetic amino acids, including but not limited to D or L optical isomers or both, amino acid analogs, and peptidomimetics. Standard single or three letter codes are used to designate amino acids.

As used herein, the term "natural L-amino acid" generally refers to glycine (G), proline (P), alanine (a), valine (V), leucine (L), isoleucine (I), methionine (M), cysteine (C), phenylalanine (F), tyrosine (Y), tryptophan (W), histidine (H), lysine (K), arginine (R), glutamine (Q), asparagine (N), glutamic acid (E), aspartic acid (D), serine (S), and threonine (T).

As used herein, the term "non-naturally occurring" generally refers to a polypeptide or polynucleotide sequence that does not correspond to, is not complementary to, or has a high degree of homology to a wild-type or naturally occurring sequence (e.g., a sequence found in a subject). For example, non-naturally occurring polypeptides or fragments may share less than 99%, 98%, 95%, 90%, 80%, 70%, 60%, 50%, or even less amino acid sequence identity when properly aligned as compared to the native sequence. Alternatively, non-naturally occurring polypeptides or fragments may share more than 99%, 98%, 95%, 90%, 80%, 70%, 60%, 50% or even more amino acid sequence identity when properly aligned as compared to the native sequence.

As used herein, the terms "hydrophilic" and "hydrophobic" generally refer to the affinity of a substance for water. Hydrophilic substances have a strong affinity for water and tend to dissolve, mix or be wetted by water, whereas hydrophobic substances essentially lack an affinity for water, tend to repel and not absorb water, and tend to be insoluble or mix or be wetted by water. Amino acids can be characterized based on their hydrophobicity. Many scales have been developed. An example is the scale developed by Levitt, M et al, J Mol Biol (1976)104:59, which is listed in Hopp, TP et al, Proc Natl Acad Sci U S A (1981)78: 3824. Examples of "hydrophilic amino acids" are arginine, lysine, threonine, alanine, asparagine, and glutamine. Of particular interest are the hydrophilic amino acids aspartic acid, glutamic acid and serine, and glycine. Examples of "hydrophobic amino acids" are tryptophan, tyrosine, phenylalanine, methionine, leucine, isoleucine and valine.

The term "fragment" when used in the context of a protein molecule (e.g., a polypeptide or protein) generally refers to a truncated form of the native biologically active protein, which may or may not retain a portion of the therapeutic and/or biological activity.

The term "variant" when used in the context of a protein molecule (e.g., a polypeptide or protein) generally refers to a protein molecule having sequence homology to a native biologically active protein that retains at least a portion of the therapeutic and/or biological activity of the biologically active protein. For example, variant proteins may share at least 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% amino acid sequence identity compared to a control biologically active protein. In some embodiments, a "variant" may include a protein that is intentionally modified, for example, by site-directed mutagenesis, synthesis of the encoding gene, insertion, or by chance by mutation.

The terms "conjugated", "linked", "fused" and "fusion" are used interchangeably herein and generally refer to the joining together of two or more chemical elements, sequences or components, for example, by means including chemical conjugation or recombination. For example, a promoter or enhancer is operably linked to a coding sequence if it affects the transcription of the sequence. Generally, "operably linked" means that the DNA sequences being linked are contiguous and in reading or reading frame. By "in-frame fusion" is meant the joining of two or more Open Reading Frames (ORFs) to form a continuous longer ORF in a manner that maintains the correct reading frame of the original ORF. Thus, the resulting "fusion polypeptide" is a single protein comprising two or more fragments corresponding to the polypeptide encoded by the original ORF (which fragments are not normally so linked in nature). "fusion site" refers to a sequence of two or more fragments joined together. In some cases, the fusion site may be a sequence identical to a sequence in two or more fragments to be joined. In some cases, the fusion site can further comprise a gap fragment that is not identical to any of the sequences of the two or more fragments being linked.

In the context of polypeptides, a "linear sequence" or "sequence" is the sequence of amino acids in a polypeptide in the amino to carboxy terminal direction, wherein residues in the sequence that are adjacent to each other are contiguous in the primary structure of the polypeptide. A "partial sequence" is a linear sequence that forms part of a polypeptide and is known to contain additional residues in one or both directions.

The terms "polynucleotide", "nucleic acid", "nucleotide" and "oligonucleotide" are used interchangeably herein, and they generally refer to a polymeric form of nucleotides of any length, i.e., deoxyribonucleotides or ribonucleotides, or analogs thereof. The polynucleotide may have any three-dimensional structure and may perform any known or unknown function. The following are non-limiting examples of polynucleotides: coding or non-coding regions of a gene or gene fragment, loci (loci or locus), exons, introns, messenger RNA (mrna), transfer RNA, ribosomal RNA, ribozymes, cDNA, recombinant polynucleotides, branched polynucleotides, plasmids, vectors, isolated DNA of any sequence, isolated RNA of any sequence, nucleic acid probes, and primers as defined by linkage analysis. Polynucleotides may comprise modified nucleotides, such as methylated nucleotides and nucleotide analogs. If present, the nucleotide structure may be modified before or after assembly of the polymer. The sequence of nucleotides may be interrupted by non-nucleotide components. The polynucleotide may be further modified after polymerization, such as by conjugation with a labeling component.

The terms "gene" and "gene fragment" are used interchangeably herein and generally refer to a polynucleotide comprising at least one open reading frame capable of encoding a particular protein following transcription and translation. The gene or gene fragment may be genomic or cDNA, so long as the polynucleotide comprises at least one open reading frame, which may cover the entire coding region or a fragment thereof. A "fusion gene" is a gene composed of at least two heterologous polynucleotides linked together.

As used herein, the term "antibody" generally refers to a protein comprising one or more polypeptides substantially encoded by immunoglobulin genes or fragments of immunoglobulin genes. Immunoglobulin genes can include kappa, lambda, alpha, gamma, delta, epsilon, and mu constant region genes, as well as myriad immunoglobulin variable region genes. As used herein, light chains can be classified as either kappa or lambda. Heavy chains can be classified as gamma, mu, alpha, delta, or epsilon, which in turn define the immunoglobulin classes, IgG, IgM, IgA, IgD, and IgE, respectively. An antibody as used herein may have a structural unit comprising a tetramer. Each tetramer can be composed of two identical pairs of polypeptide chains, each pair having one "light" (about 25kD) and one "heavy" chain (about 50-70 kD). The N-terminus of each chain may define a variable region of about 100 to 110 or more amino acids, which is primarily responsible for antigen recognition. As used herein, the terms "light chain variable region" (VL) and "heavy chain variable region" (VH) generally refer to these regions of the light and heavy chains, respectively. Antibodies may exist as intact immunoglobulins or as a number of well-characterized fragments produced by digestion with various peptidases or expressed de novo. Thus, for example, pepsin can digest the antibody below the disulfide bonds in the hinge region to produce f (ab)'2 (a dimer of Fab, which is itself a light chain linked to VH-CH1 by disulfide bonds). F (ab) '2 can be reduced under mild conditions to disrupt the disulfide bonds in the hinge region, thereby converting the (Fab ')2 dimer into a Fab ' monomer. The Fab' monomer is essentially an Fab with a partial hinge region (see basic Immunology, edited by paul, Raven press, new york (1993)) for a more detailed description of other antibody fragments. Although various antibody fragments are defined in terms of digestion of intact antibodies, one of ordinary skill in the art will appreciate that such Fab' fragments can be synthesized de novo either chemically or using recombinant DNA methods. Thus, the term antibody as used herein may also include antibody fragments synthesized de novo by modifying whole antibodies or using recombinant DNA methods, including but not limited to Fab'2, IgG, IgM, IgA, IgE, scFv, dAb, nanobodies, single antibodies, and diabodies. In some embodiments, antibodies include, but are not limited to, Fab'2, IgG, IgM, IgA, IgE, and single chain antibodies, e.g., single chain fv (scfv) antibodies in which a variable heavy chain and a variable light chain are linked together (either directly or through a peptide linker) to form a continuous polypeptide.

As used herein, the term "antigen binding site" or "binding portion" generally refers to a portion of an antibody that is involved in antigen binding. The antigen binding site may be formed from amino acid residues of the N-terminal variable ("V") region of the heavy ("H") chain and/or the light ("L") chain. The three highly divergent stretches within the V regions of the heavy and light chains are called "hypervariable regions" and they are located between the more conserved flanking segments, called "framework regions" or "FRs". Thus, the term "FR" as used herein generally refers to amino acid sequences that naturally occur between and adjacent to hypervariable regions in immunoglobulins. In an antibody molecule, the three hypervariable regions of the light chain and the three hypervariable regions of the heavy chain are arranged relative to each other in three-dimensional space to form an antigen-binding "surface". The surface may mediate the recognition and binding of the target antigen. The three hypervariable regions of each of the heavy and light chains are referred to as "complementarity determining regions" or "CDRs" and are characterized, for example, by Kabat et al, "Sequences of proteins of immunological interest," 4 th edition, department of health and public service, public health service, bessel, maryland (1987).

In some embodiments, the antibodies and fragments thereof used herein may be bispecific. Bispecific antibodies or fragments thereof can have various configurations. For example, a bispecific antibody may resemble a single antibody (or antibody fragment), but have two different antigen binding sites (variable regions). In various embodiments, bispecific antibodies can be produced by chemical techniques (Kranz et al (1981) proc.natl.acad.sci., usa, 78:5807), by "polyoma" techniques (see, e.g., U.S. patent No. 4,474,893), or by recombinant DNA techniques. In some embodiments, a bispecific antibody used herein can have binding specificities for at least two different epitopes, at least one of which is a tumor antigen. In some embodiments, the antibodies and fragments thereof may also be alloantibodies. A xenogenous antibody is two or more antibodies or antibody binding fragments (e.g., fabs) linked together, each antibody or fragment having a different specificity.

As used herein, the terms "homology," "homologous," or "sequence identity" generally refer to sequence similarity or interchangeability between two or more polynucleotide sequences or between two or more polypeptide sequences. When using programs (e.g., Emboss Needle or BestFit) to determine sequence identity, similarity or homology between two different amino acid sequences, default settings may be used, and appropriate scoring matrices (such as blosum45 or blosum80) may be selected to optimize the identity, similarity or homology scores. In some embodiments, homologous polynucleotides are those that hybridize under stringent conditions and have at least 60%, at least 65%, at least 70%, at least 80%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or even 100% sequence identity to these sequences. When sequences of comparable length are optimally aligned, homologous polypeptides have at least 80% or at least 90% or at least 95% or at least 97% or at least 98% or at least 99% sequence identity.

The terms "percent identity" and "% identity" as used in the context of polynucleotide sequences generally refer to the percentage of residue matches between at least two polynucleotide sequences that are aligned using a standardized algorithm. Such algorithms can insert gaps in the compared sequences in a standardized and reproducible manner to optimize the alignment between the two sequences, thereby achieving a more meaningful comparison of the two sequences. Percent identity may be measured over the length of the entire defined polynucleotide sequence, or may be measured over a shorter length, such as over the length of a fragment obtained from a larger defined polynucleotide sequence. It is understood that any fragment length supported by the sequences shown herein, in the tables, figures, or sequence listing can be used to describe the length over which percent identity can be measured.

The term "percent (%) sequence identity," as used in the context of polypeptide sequences identified herein, generally refers to the percentage of amino acid residues in the query sequence that are identical to the amino acid residues of a second, reference polypeptide sequence, after aligning the sequences and introducing gaps, if necessary, a portion of the sequence or a portion thereof can be achieved to achieve the maximum percent sequence identity, and no conservative substitutions are considered as part of the sequence identity. Alignments to determine percent amino acid sequence identity can be performed in a variety of ways within the skill in the art, for example, using publicly available computer software, such as BLAST, BLAST-2, ALIGN, needlet, or megalign (dnastar) software. One skilled in the art can determine suitable parameters for measuring alignment, including any algorithms required to achieve maximum alignment over the full length of the sequences being compared. The percent identity may be measured over the length of the entire defined polypeptide sequence, or may be measured over a shorter length, for example, over the length of a fragment obtained from a larger defined polypeptide sequence. It is understood that any fragment length supported by the sequences shown herein, in the tables, figures, or sequence listing can be used to describe the length over which percent identity can be measured.

The progeny may not necessarily be identical (morphologically or in the genome of the total DNA complement) to the original parent cell due to natural, accidental, or deliberate mutation. Host cells may include cells transfected in vitro with a vector of the present application. The host cell may be a bacterial cell (e.g., E.coli), yeast cell, or other eukaryotic cell, such as a COS cell, Chinese Hamster Ovary (CHO) cell, HeLa cell, HEK293 cell, COS-1 cell, NS0 cell, or myeloma cell. In some embodiments, the host cell is a mammalian cell. In some embodiments, the mammalian cell is a HEK293 cell.

Also included are vectors that provide one of the above functions. An "expression vector" is a polynucleotide that, when introduced into a suitable host cell, can be transcribed and translated into a polypeptide. "expression system" generally refers to a suitable host cell containing an expression vector that can be manipulated to produce a desired expression product.

The term "effective amount" or "therapeutically effective amount" refers to an amount of a composition (e.g., a protein heterodimer described herein) sufficient to effect the intended use, including but not limited to, the treatment of a disease. The therapeutically effective amount may vary depending on the intended application (e.g., in vitro or in vivo) or the subject and the disease condition being treated (e.g., weight and age of the subject, severity of the disease condition, mode of treatment). The mode of administration and the like can be readily determined by one of ordinary skill in the art. The term may also apply to doses that will induce a specific response in the target cell, e.g. targeted gene induction, proliferation and/or apoptosis. The specific dosage will vary depending upon the particular compound selected, the administration regimen to be followed, whether or not to be administered in combination with other compounds, the time of administration, the tissue being administered, and the physical delivery system in which the administration is to occur.

The terms "treatment" or "treating" or "palliating" or "ameliorating" are used interchangeably herein and refer to a method of achieving a beneficial or desired result, including but not limited to a therapeutic benefit and/or a prophylactic benefit. As used herein, therapeutic benefit generally refers to eradication or reduction of the severity of the underlying disease being treated. Likewise, therapeutic benefit is achieved by eliminating, reducing the severity of, or reducing the incidence of one or more physiological symptoms associated with the underlying disease, such that an improvement is observed in the subject despite the fact that the subject may still be suffering from the underlying condition. For prophylactic benefit, the composition may be administered to a subject at risk of having a particular disease, or to a subject reporting one or more physiological symptoms of a disease, even though the disease may not have been diagnosed.

As used herein, the term "therapeutic effect" generally includes a therapeutic benefit and/or a prophylactic benefit as described above.

As used herein, the terms "co-administration," "co-administration with … …," and grammatical equivalents thereof, generally include administration of two or more agents to an animal such that the agents and/or metabolites thereof are present in the subject at the same time. Co-administration includes simultaneous administration in separate compositions, administration at different times in separate compositions, or administration in a composition in which both agents are present.

The terms "antagonist" and "inhibitor" are used interchangeably herein and generally refer to a compound that has the biological function of inhibiting a target protein by inhibiting its activity or expression. Thus, the terms "antagonist" and "inhibitor" are defined in the context of the biological effects of the target protein. Although the preferred antagonists herein specifically interact with (e.g., bind to) the target, compounds that inhibit the biological activity of the target protein by interacting with other members of the signal transduction pathway of which the target protein is a member are also expressly included within this definition. The preferred biological activity inhibited by the antagonist is associated with the development, growth or spread of a tumor.

As used herein, the term "agonist" generally refers to a compound that has the ability to initiate or enhance a biological function of a target protein by inhibiting or enhancing the activity or expression of the target protein. Thus, the term "agonist" is defined in the context of the biological effect of the target polypeptide. Although preferred agonists herein specifically interact with (e.g., bind to) the target, compounds that elicit or enhance the biological activity of the target polypeptide by interacting with other members of the signal transduction pathway of which the target polypeptide is a member are also specifically included in this definition.

In some embodiments, the interleukin may be in a mutant form, e.g., with increased or decreased affinity for its receptor. In a particular embodiment, the interleukin may be a super IL-2 (also known as sIL2, see Nature 484, 529-533, 26/4/2012) obtainable by modifying IL-2 to increase its binding affinity for IL-2R β. The mutation of sIL-2 is mainly located in the core of cytokine, and molecular dynamics simulation shows that the evolved mutation stabilizes IL-2, thereby reducing the flexibility of IL-2R beta binding site helix and becoming the optimal conformation similar to a receptor. When bound to CD 25. As compared to IL-2, sIL-2 induces superior expansion of cytotoxic T cells, thereby increasing the in vivo anti-tumor response and proportionally reducing T regulatory cell expansion and reducing pulmonary edema.

Protein heterodimers, protein mixtures, isolated polynucleotides, vectors and host cells

In one aspect, the present application provides protein heterodimers. The protein heterodimer may comprise a first member and a second member different from the first member. The first member can comprise a light chain and a heavy chain comprising a first Fc region, and the light chain can be complexed with the heavy chain to form a targeting moiety that exhibits binding specificity to a tumor antigen. The second member may comprise a polypeptide, and the polypeptide comprises an immunomodulator fused to the second Fc region. The first member and the second member may associate through complexation of the first Fc region and the second Fc region to form a heterodimer.

In some cases, a protein heterodimer of the present application can be a protein complex. The complex can comprise at least three polypeptide chains, e.g., a first polypeptide chain, a second polypeptide chain, and a third polypeptide chain. In some embodiments, the complex consists of, or consists essentially of, three polypeptide chains. For example, the first polypeptide chain can comprise a heavy chain of an antibody specific for a tumor antigen and the second polypeptide chain can comprise a light chain of an antibody specific for a tumor antigen. The heavy chain may comprise a first Fc region. The heavy chain (i.e., the heavy chain of the first polypeptide chain) and the light chain (i.e., the light chain of the second polypeptide chain) can complex to form a first member of a protein heterodimer. The third polypeptide chain can comprise (e.g., from N-terminus to C-terminus) one or more immunomodulatory agents fused to the second Fc region, optionally via one or more linkers. The third polypeptide chain can be a second member of a protein heterodimer. The first member and the second member may associate through complexation of the first Fc region with the second Fc region to form a heterodimer.

For example, a protein heterodimer of the present application can be a protein complex that can comprise (1) heavy and light chains of an antibody specific for a tumor antigen; (2) a fusion protein comprising, from N-terminus to C-terminus, one or more immunomodulators fused to an antibody Fc region, optionally via one or more linkers.

The first Fc region may comprise a first modification, and/or the second Fc region may comprise a second modification, wherein the first modification and/or the second modification may promote heterodimerization between the first member and the second member more effectively than a nodal-pore modification comprising a nodal modification and a pore modification. For example, the first modification may be in the CH3 domain of the first Fc region and the second modification may be in the CH3 domain of the second Fc region. For example, the first modification and/or the second modification are each compared to the sequence of its corresponding wild-type Fc region.

Polynucleotides can be synthesized using recombinant techniques well known in the art. For example, polynucleotides can be synthesized by using an automated DNA synthesizer.

Standard recombinant DNA and molecular cloning techniques include those described below: sambrook, j., Fritsch, e.f., and manitis, t. molecular cloning: a Laboratory Manual (Molecular Cloning: A Laboratory Manual); cold spring harbor laboratory press: cold spring harbor, (1989) (Maniatis) and t.j.silhavy, m.l.bennan and l.w.enquist, Experiments with Gene Fusions, cold spring harbor laboratory, cold spring harbor in new york (1984) and Ausubel, f.m. et al, Current Protocols in molecular Biology, greens publishing association and Wiley-Interscience publication (1987). Briefly, the nucleic acids of the present application can be prepared from genomic DNA fragments, cDNA and RNA, all of which can be extracted directly from cells or recombinantly produced by various amplification methods, including but not limited to PCR and RT-PCR.

Direct chemical synthesis of nucleic acids typically involves sequential addition of 3' -blocked and 5' -blocked nucleotide monomers to the terminal 5' hydroxyl group of a growing nucleotide polymer chain, where each addition is affected by nucleophilic attack of the terminal 5' hydroxyl group of the growing chain on the 3' position of the added monomer, which is typically a phosphorus derivative, such as a phosphotriester, phosphoramidite, and the like. See, e.g., Matteuci et al, tetrahedron letters (Tet. Lett.)521:719 (1980); U.S. patent No. 4,500,707 to carothers et al; and Southern et al U.S. patent nos. 5,436,327 and 5,700,637.

The vector may be any linear nucleic acid, plasmid, phagemid, cosmid, RNA vector, viral vector, or the like. Non-limiting examples of viral vectors can include retroviruses, adenoviruses, and adeno-associated viruses. In some embodiments, the vector is an expression vector, such as a phage display vector.

Expression vectors may be adapted for a particular type of host cell and not for other types. For example, an expression vector may be introduced into a host organism and its viability and expression of any genes/polynucleotides contained in the vector monitored.

The expression vector may also contain one or more selectable marker genes that confer one or more phenotypic traits upon expression, and may be used to select for or otherwise identify the host cell carrying the expression vector. Non-limiting examples of suitable selectable markers for eukaryotic cells include dihydrofolate reductase and neomycin resistance.

The subject vectors may be stably or transiently introduced into host cells by a variety of established techniques. For example, one approach involves calcium chloride treatment, wherein the expression vector is introduced via a calcium precipitate. Other salts, such as calcium phosphate, may also be used in a similar procedure. In addition, electroporation (i.e., application of an electric current to increase the permeability of a cell to nucleic acids) can be used. Other examples of transformation methods include microinjection, DEAE dextran-mediated transformation, and heat shock in the presence of lithium acetate. Lipid complexes, liposomes and dendrimers can also be used to transfect host cells.

After introduction of the heterologous sequence into a host cell, various methods can be practiced to identify the host cell into which the subject vector has been introduced. One exemplary selection method involves subculturing individual cells to form individual colonies, which are then tested for expression of the desired protein product. Another approach entails selecting host cells containing heterologous sequences based on a phenotypic trait conferred by expression of a selectable marker gene contained in an expression vector.

For example, the introduction of various heterologous sequences of the present application into a host cell can be confirmed by methods such as PCR, Southern blot, or Northern blot hybridization. For example, nucleic acids can be prepared from the resulting host cells, and target-specific sequences can be amplified by PCR using primers specific for the target sequences. The amplified product is subjected to agarose gel electrophoresis, polyacrylamide gel electrophoresis or capillary electrophoresis, and then stained with ethidium bromide, SYBR Green solution, or the like, or DNA is detected by UV detection. Alternatively, a nucleic acid probe specific for a sequence of interest may be used in the hybridization reaction. Expression of a particular gene sequence can be determined by reverse transcription coupled with PCR, Northern blot hybridization, or immunoassay using an antibody reactive with the encoded gene product to detect the corresponding mRNA. Exemplary immunoassays include, but are not limited to, ELISA, radioimmunoassays, and sandwich immunoassays.

In addition, the introduction of various heterologous sequences of the present application into a host cell can be demonstrated by the enzymatic activity of an enzyme (e.g., an enzyme label) encoded by the heterologous sequence. The enzyme can be determined by a variety of methods known in the art. In general, enzyme activity can be determined by the formation of products or the conversion of substrates of the enzymatic reaction under investigation. The reaction may be carried out in vitro or in vivo.

In another aspect, the present application provides an isolated host cell comprising an isolated polynucleotide or vector of the present application, and/or an isolated polynucleotide capable of expressing a protein heterodimer, and/or an isolated polynucleotide encoding a protein heterodimer, and/or a protein mixture of the present application.

In some embodiments, the cell expresses a heterodimeric protein of the present application and the isolated polynucleotide encodes a heterodimeric protein and/or a mixture of proteins of the present application. The cell may be a eukaryotic cell or a prokaryotic cell.

The examples and formulations provided below further illustrate and exemplify the protein heterodimers of the present application and methods of use and preparation thereof. It should be understood that the scope of the present application is not in any way limited by the following examples and preparation ranges.

Example 1: modification and preparation of polypeptides

1.1 determination of amino acid modifications in the Fc region

The interfacial amino acid residues of the CH3-CH3 domain of human IgG1 were determined. Wild type human IgG1 comprised a first heavy chain (chain a) and a second heavy chain (chain B), the interfacial amino acids of each of chain a and chain B are shown in table 1 below, and the amino acid positions are determined according to the EU index of KABAT numbering:

TABLE 1 CH3-CH3 interfacial residues in the Fc region of wild-type human IgG1 antibody (PDB No. 1DN2)

Amino acid modifications (e.g., amino acid substitutions) are then made to the interface residues to obtain the following set of modifications (shown in table 2 below, referenced to KH knuckle modification), in this application, chain a is also referred to as Fc9 or a first Fc region and chain B is also referred to as Fc6 or a second Fc region:

TABLE 2 amino acid modification group

Subsequently, the formation of heterodimeric proteins comprising the modification groups listed in table 2 above was examined using the ScFv-Fc/Fc system, as explained in detail below.

First, the amino acid sequence of the constant region of human immunoglobulin gamma 1(IgG1) was obtained from the database Unit (P01857) to obtain the amino acid sequence of the wild-type human IgG1-Fc region (SEQ ID NO: 30). A polynucleotide fragment encoding wild-type human IgG1-Fc was obtained by RT-PCR from human PBMC total RNA (SEQ ID NO: 31, referred to as Fc gene fragment). A polynucleotide fragment encoding the mouse kappa III signal peptide (SEQ ID NO: 32) was added to the 5' end of the Fc gene by overlap PCR and then subcloned into the vector pcDNA4(Invitrogen, cat # V86220) to obtain recombinant expression. Vector for expression of human IgG1-Fc in mammalian cells.

In some cases, a polypeptide encoding the variable region (VhH) of a camelid single domain antibody is fused to the N-terminus of an Fc gene fragment to obtain a fusion gene fragment (shown as SEQ ID NO: 33) encoding fusion protein VhH-Fc (shown as SEQ ID NO: 34). It was then subcloned into the vector pcDNA4(Invitrogen, cat # V86220) to obtain a recombinant expression vector for expression of the fusion protein VhH-Fc in mammalian cells.

A nucleic acid molecule (SEQ ID NO: 35) encoding an ScFv-Fc fusion protein was synthesized, wherein ScFv refers to an anti-Her 2 single-chain antibody, and the amino acid sequence of the ScFv-Fc fusion protein is shown in SEQ ID NO: shown at 36. The ScFv-Fc gene fragment was then subcloned into vector pcDNA4(Invitrogen, cat # V86220) to obtain a recombinant expression vector for expression of ScFv-Fc fusion protein in mammalian cells.

The amino acid modifications listed in Table 2 above were then introduced by overlap PCR into ScFv-Fc (KH and groups 1-17), VhH-Fc (groups 9-12, 14, 15 and 17) and the Fc gene fragment (groups KH and 1-8), respectively, where chain A refers to the Fc region in ScFv-Fc and chain B refers to the Fc region in either independent or VhH-Fc. The gene fragments with amino acid modifications were subcloned into vector pcDNA4(Invitrogen, cat # V86220), respectively, to obtain recombinant expression vectors for expression of modified ScFv-Fc fusion protein, modified Fc protein and modified VhH-Fc fusion protein in mammalian cells.

Then, HEK293 cells (ATCC CRL-1573. TM.) cultured in suspension were transfected with the constructed expression vector carrying PEI. For each group, the expression vector expressing a chain (ScFv-Fc fusion protein) and the expression vector expressing B chain (Fc protein or VhH-Fc fusion protein) were mixed at a ratio of 1: 1 ratio co-transfection. After 5-6 days of culture, the supernatant of the transient expression product was collected and the expression product containing the corresponding protein heterodimer was preliminarily purified using protein a affinity chromatography. Each of the preliminarily purified expression products contained the homodimeric protein ScFv-Fc/ScFv-Fc, the homodimeric protein Fc/Fc (or homodimeric protein VhH-Fc/VhH-Fc) and the heterodimeric protein ScFv-Fc/Fc (or heterodimeric protein ScFv-Fc/VhH-Fc), respectively, present in different percentages. Because of the different molecular weights of these proteins (i.e., homodimers and heterodimers), their respective percentages can be determined from the corresponding band intensities reflected on the unreduced SDS-PAGE gels. The intensities were quantified and the results are summarized in tables 3-6 below.

Table 3 shows the percentage of homodimeric protein and heterodimeric protein in the products

Table 4 expresses the percentage of homodimeric protein and heterodimeric protein in the product

Table 5 expression of the product of homodimeric protein and heterodimeric protein percentage

Table 6 shows the percentage of homodimeric protein and heterodimeric protein in the products

As can be seen from tables 3-6 above, all of the modification groups promoted heterodimer formation more efficiently than the reference modified nodal pores. For illustrative purposes, the modifications in set 10 (modification in chain A: T366W + K409A; modification in chain B: T366S + L368G + Y407A + F405K) were used in the following examples to generate the protein heterodimers or protein mixtures of the present application.

After two days, the cell suspension was centrifuged and then weighedSuspended in 100 mLFreeestyle 293 medium. The expression plasmids were classified into "Erb- (huIL10)2-6-9 group" and "Erb- (huIL10)2-KH group", wherein the Erb- (huIL10)2-6-9 group contained: pcDNA4-Erb-Fc9 (33. mu.g) + pcDNA4-Erb-LC (33. mu.g) + pcDNA4- (huIL10)2-Fc6 (33. mu.g); the Erb- (huIL10)2-KH group comprises: pcDNA4-Erb-Knob (33. mu.g) + pcDNA4-Erb-LC (33. mu.g) + pcDNA4- (huIL10) 2-Fc-well (33. mu.g). Each set of plasmid mixtures was diluted with 1mL of Freestyle293 medium and transfected with PEI (polyethyleneimine) solution. Each set of plasmid/PEI mixtures was added to 100mL of cell suspension separately, followed by 10% CO at 37 ℃₂The culture was carried out at 90rpm, and 50. mu.g/L of IGF-1 was added to the medium. After 4 hours, the culture was supplemented with 100mL of EX293 medium, 2mM glutamine and 50. mu.g/L IGF-1, and cultured at 135 rpm. After 24 hours, 3.8mM VPA was added. After 5-6 days, the transiently expressed culture supernatant was collected and the expression product containing the corresponding protein heterodimer was primarily purified using protein a affinity chromatography. The primarily purified expression products from the Erb- (huIL10)2-6-9 group contained the homodimeric protein Erb-Fc9/Erb-Fc9, homodimeric protein (huIL10)2-Fc6/(huIL10)2-Fc6, and heterodimeric protein Erb-Fc9/(huIL10)2-Fc6, present in different percentages, respectively.

Due to the different molecular weights of these proteins (i.e., homodimers and heterodimers), their respective percentages can be determined from the respective band intensities reflected on the unreduced SDS-PAGE gels, as shown in FIG. 3. Lane 1 is loaded with an antibody control (erbitux), lane 2 is loaded with the expression product of Erb- (huIL10)2-KH group, and lane 3 is loaded with the expression product of Erb- (huIL10)2-6-9 group.

Thus, the protein heterodimers of the present application comprise modifications that promote heterodimer formation more efficiently than the corresponding protein heterodimers comprising nodal pore modifications.

4.2 comparison of heterodimer Erb-husIL2-6-9 with the reference protein Erb-husIL2-KH heterodimer formation

Two days prior to transfection, 2X 100mL suspension acclimatized HEK293(ATCC, CRL-1573) was prepared^TM) Cells were used for transient transfection and were transfected at 0.8X 10⁶Cells were seeded at a density of cells/mL. After two days, the cell suspension was centrifuged and then resuspended in 100ml of lfreeestyle 293 medium. The expression plasmids were divided into "Erb-husIL 2-6-9 group" and "Erb-husIL 2-KH group", wherein the Erb-husIL2-6-9 group contained: pcDNA4-Erb-Fc9 (33. mu.g) + pcDNA4-Erb-LC (33. mu.g) + pcDNA4-husIL2-Fc6 (33. mu.g); the Erb-husIL2-KH group includes: pcDNA4-Erb-Knob (33. mu.g) + pcDNA4-Erb-LC (33. mu.g) + pcDNA4-husIL 2-Fc-well (33. mu.g). Each set of plasmid mixtures was diluted with 1mL of Freestyle293 medium and transfected with PEI (polyethyleneimine) solution. Each set of plasmid/PEI mixtures was added to 100mL of cell suspension separately, followed by 10% CO at 37 ℃₂Culturing at 90rpm, and adding to the medium50. mu.g/L IGF-1 was added. After 4 hours, the culture was supplemented with 100mL of EX293 medium, 2mM glutamine and 50. mu.g/L IGF-1, and cultured at 135 rpm. After 24 hours, 3.8mM VPA was added. After 5-6 days, the transiently expressed culture supernatant was collected and the expression product containing the corresponding protein heterodimer was primarily purified using protein a affinity chromatography. The primarily purified expression products from the Erb-husIL2-6-9 group contained the homodimeric protein Erb-Fc9/Erb-Fc9, the homodimeric protein husIL2-Fc6/husIL2-Fc6, and the heterodimeric protein Erb-Fc9/husIL2-Fc6, respectively, present in different percentages. The primary purified expression products from the Erb-husIL2-KH group contained the homodimeric protein Erb-knob/Erb-knob, the homodimeric protein husIL 2-well/husIL 2-well, and the heterodimeric protein Erb-knob/husIL 2-well, present in different percentages. Due to the different molecular weights of these proteins (i.e., homodimers and heterodimers), their respective percentages can be determined from the respective band intensities reflected on the unreduced SDS-PAGE gels, as shown in FIG. 3. Lane 7 is loaded with the antibody control (erbitux), lane 8 with the expression product of Erb-husIL2-KH group, and lane 9 with the expression product of Erb-husIL2-6-9 group.

Lanes

8 percent protein homodimers and heterodimers

Example 5: comparison of expression products with different modifications

As shown in example 4, the protein heterodimers of the present application comprise modifications that promote heterodimer formation more effectively than the corresponding protein heterodimers comprising nodal pore modifications.

To further examine the effect of the first and second modifications, we compared the following expression products:

group 2: pcDNA4-Erb-Fc6+ pcDNA4-Erb-LC + pcDNA4- (huIL10)2-Fc 9; and

group 3: pcDNA4-Erb-Fc9+ pcDNA4-Erb-LC + pcDNA4- (huIL10)2-Fc6

As described above in example 3.

Briefly, two days prior to transfection, 2X 100mL suspension acclimatized HEK293(ATCC, CRL-1573) was prepared^TM) Cells were used for transient transfection and were transfected at 0.8X 10⁶Cells were seeded at a density of cells/mL. After two days, the cell suspension was centrifuged and then resuspended in 100mL Freestyle293 medium. The expression plasmids were divided into "Erb- (huIL10)2-6-9 group" and "Erb- (huIL10)2-9-6 group", wherein Erb- (huIL10)2-6-9 group contained: pcDNA4-Erb-FC9(33 μ g) + pcDNA4-ERB-LC (33 μ g) + pcDNA4- (huIL10)2-FC6(33 μ g); erb- (huIL10) groups 2-9-6 contained: pcDNA4-Erb-Fc6 (33. mu.g) + pcDNA4-Erb-LC (33. mu.g) + pcDNA4- (huIL10)2-Fc9 (33. mu.g). Each plasmid mixture was diluted with 1mL of LFreeestyle 293 medium and transfected with PEI (polyethyleneimine) solution. Each set of plasmid/PEI mixtures was added to 100mL of cell suspension separately, followed by 10% CO at 37 ℃₂The cells were cultured at 90rpm, and 50. mu.g/LIGF-1 was added to the medium. After 4 hours, the culture was supplemented with 100mL of EX293 medium, 2mM glutamine and 50. mu.g/L IGF-1, and cultured at 135 rpm. After 24 hours, 3.8mM VPA was added. After 5-6 days, the transiently expressed culture supernatant was collected and the expression product containing the corresponding protein heterodimer was primarily purified using protein a affinity chromatography. The primarily purified expression products from the Erb- (huIL10)2-6-9 group contained the homodimeric protein Erb-Fc9/Erb-Fc9 (i.e., Fc9 homodimer), homodimeric protein (huIL10)2-Fc6/(huIL10)2-Fc6 (i.e., Fc6 homodimer), and heterodimeric protein Erb-Fc9/(huIL10)2-Fc6, present in different percentages, respectively. The primarily purified expression products from the Erb- (huIL10)2-9-6 group included the homodimeric protein Erb-Fc6/Erb-Fc6 (i.e., Fc6 homodimer), homodimeric protein (huIL10)2-Fc9/(huIL10)2-Fc9 (i.e., Fc9 homodimer), and heterodimeric protein Erb-Fc6/(huIL10)2-Fc9, present in different percentages, respectively. ByThe molecular weights of these proteins (i.e., homodimers and heterodimers) differ, and therefore their respective percentages can be determined from the corresponding band intensities reflected on unreduced SDS-PAGE gels, as shown in FIG. 4. Lane 1 is loaded with a standard protein marker, lane 2 with the expression products of Erb- (huIL10)2-6-9 group, and lane 3 with the expression products of Erb- (huIL10)2-9-6 group. As can be seen from FIG. 4, in lane 2, the majority of homodimers (i.e., undesired impurities in the protein mixture) formed were the Erb-Fc9/Erb-Fc9 homodimers (i.e., Fc9 homodimers), as indicated by the 85KD band (the Erb-Fc9/Erb-Fc9 homodimers are very unstable and readily dissociate into monomers with a molecular weight of about 85 KD). Interestingly and surprisingly, in lane 3, the majority of homodimers (i.e. undesired impurities in the protein mixture) formed were (huIL10)2-Fc9/(huIL10)2-Fc9 homodimers (i.e. Fc9 homodimers), as indicated by the band between 50KD and 85KD ((huIL10)2-Fc9/(huIL10)2-Fc9 homodimers being very unstable and readily dissociating into monomers with molecular weights between 50KD and 85 KD). Thus, the tendency to form the Erb-Fc9/Erb-Fc9 homodimer is not due to the Erb moiety, but rather to the Fc9 moiety.

Thus, members of the protein heterodimer comprising the Fc9 region are intended to cause the formation of undesired homodimer impurities. Thus, in the protein heterodimers of the present application, it is more advantageous to fuse an immunomodulator (such as a cytokine) to the Fc6 domain (i.e., the second Fc region) rather than the Fc9 domain (i.e., the first Fc region).

Example 6: binding of protein heterodimers to the corresponding targets

6.1 binding of Erb-Interferon protein heterodimers to EGFR

The binding of Erb-interferon protein heterodimers to EGFR was examined using the human squamous cell carcinoma A431 cell line. Flow cytometry analysis was used, in which serial dilutions of the Erb-interferon protein heterodimer (or control Erb antibody (erbitux, Merck)) of the present application and anti-human IgG Fc-specific PE (eBioscience: 12-4998-82) secondary antibodies were added sequentially into the cells. Then, flow cytometry analysis was performed and dose-response curves were plotted with protein concentration and Medium Fluorescence Intensity (MFI) from PE channels. As shown in fig. 5, the protein heterodimer Erb-huIFNa2-6-9 specifically binds to target EGFR in a manner similar to the control antibody cetuximab (erbitux). Since the protein heterodimer contains only one EGFR-binding moiety, its EC50 is higher than the EC50 of the control antibody cetuximab, which contains two EGFR-binding moieties.

The binding affinity of Erb-huIFNa2-6-9 to its target EGFR was also tested by biolayer interferometry (BLI) compared to the control antibody cetuximab. The experiment was performed using octet K2. Protein a biosensors and EGFR-His protein were used. FIG. 6 shows the binding affinity of Erb-huIFNa2-6-9 and cetuximab to EGFR-His. The results show that there was no significant difference in the binding affinity of Erb-huIFNa2-6-9 to EGFR-His from the binding affinity of the control antibody cetuximab.

6.2 binding of Erb-Interleukin protein heterodimer to EGFR

The binding of Erb-interleukin protein heterodimer to EGFR was examined using the human squamous cell carcinoma A431 cell line. Flow cytometry analysis was used in which serial dilutions of the Erb-interleukin protein heterodimer (or control Erb antibody (erbitux, Merck)) of the present application and anti-human IgG Fc-specific PE (eBioscience: 12-4998-82) secondary antibody were added sequentially into the cells. Then, flow cytometry analysis was performed and dose-response curves were plotted with protein concentration and Medium Fluorescence Intensity (MFI) from PE channels. As shown in fig. 5, the protein heterodimer Erb- (huIL10)2-6-9 specifically binds to target EGFR in a manner similar to the control antibody cetuximab. Since the protein heterodimer contains only one EGFR-binding moiety, its EC50 is higher than the EC50 of the control antibody cetuximab, which contains two EGFR-binding moieties.

The binding affinity of Erb- (huIL10)2-6-9 to its target EGFR was also measured by biolayer interferometry (BLI) compared to the control antibody cetuximab. The experiment was performed using octet K2. Protein a biosensors and EGFR-His protein were used. The respective binding affinities of Erb- (huIL10)2-6-9 and cetuximab to EGFR-His are shown in FIG. 6. The results show that there was no significant difference in the binding affinity of Erb- (huIL10)2-6-9-9 to EGFR-His from the binding affinity of control cetuximab.

6.3 binding of Mab 806-Interferon and Mab 806-Interleukin protein heterodimers to EGFR

The binding of Mab806-huIFNa2-6-9 and Mab806- (huIL10)2-6-9 to EGFRVIII was tested using a mouse colon cancer cell line (i.e., the MC38 cell line) that stably expresses human EGFRvIII. Mab806 is an antibody that binds to the EGFRvIII mutant, however, it can also bind to wild-type EGFR with low affinity. Flow cytometry was performed and the results are shown in fig. 7. As can be seen from FIG. 7, Mab806-huIFNa2-6-9 and Mab806- (huIL10)2-6-9 bound to EGFRvIII expressed on MC38 cells.

6.4 Tma-binding of interleukin protein heterodimer to Her2

Similarly, Tmab- (huIL10)2-6-9 heterodimer was also tested for binding to Her2, experiments were performed using a mouse colon cancer cell line stably expressing human Her2 (i.e., MC38 cell line) and a melanoma cell line stably expressing human Her2 (i.e., B16 cell line). The results are shown in group (a) (MC38 cells) and group (B) (B16 cells) of fig. 8, respectively. As can be seen from FIG. 8, Tmb- (huIL10)2-6-9 binds to Her2 expressed on MC38 or B16 cells. Similar results were also obtained for the Pmab-interleukin protein heterodimer (e.g., Pmab- (huIL10) 2-6-9).

6.5 binding of C-mab-Interferon and C-mab-Interleukin protein heterodimers to GPC3

The binding of C-mab-huIFNa2-6-9 and C-mab- (huIL10)2-6-9 to GPC3 was tested using a mouse colon cancer cell line (MC38 cell line) that stably expresses human GPC 3. Flow cytometry was performed and the results are shown in fig. 9. As can be seen in FIG. 9, C-mab-huIFNa2-6-9 and C-mab- (huIL10)2-6-9 bound to GPC3 expressed on MC38 cells.

6.628H 1 interferon and 28H1 interleukin protein heterodimer binding to FAP

Binding of 28H1-huIFNa2-6-9 and 28H1- (huIL10)2-6-9 to FAP was detected using a mouse colon cancer cell line (MC38 cell line) expressing human FAP. Flow cytometry was performed and the results are shown in fig. 10. As can be seen in FIG. 10, 28H1-huIFNa2-6-9 and 28H1- (huIL10)2-6-9 bound to FAP expressed on MC38 cells.

6.75E 5 binding of Interferon and 5E5 Interleukin protein heterodimers to MUC1

The binding of 5E5-huIFNa2-6-9 and 5E5- (huIL10)2-6-9 to MUC1 was tested using a human breast cancer cell line (T-47D cell line) expressing human MUC 1. Flow cytometry was performed and the results are shown in fig. 21. As can be seen in FIG. 21, 5E5-huIFNa2-6-9 and 5E5- (huIL10)2-6-9 bound to MUC1 expressed on T-47D cells.

6.8 binding of Enstauximab-Interferon and Enstauximab-Interleukin protein heterodimers to MUC5AC

The binding of E-mab-huIFNa2-6-9 and E-mab- (huIL10)2-6-9 to MUC5AC was tested using a human pancreatic cancer cell line (CFPAC-1 cell line) expressing human MUC5 AC. Flow cytometry was performed and the results are shown in fig. 22. As can be seen in FIG. 22, the binding of E-mab-huIFNa2-6-9 and E-mab- (huIL10)2-6-9 to MUC5AC expressed on CFPAC-1 cells was not very strong. This is probably due to the potential underexpression of the particular protein glycoform found in situ in tumor tissue, and it is known that E-mab binds strongly to the particular protein glycoform.

6.9 binding of Amadoximab-Interferon and Amadoximab-Interleukin protein heterodimers to Mesothelin

The binding of A-mab-huIFNa2-6-9 and A-mab- (huIL10)2-6-9 to mesothelin was examined using a human gastric carcinoma cell line expressing human mesothelin (NCI-N87 cell line). Flow cytometry was performed, and the results are shown in fig. 23. As can be seen from FIG. 23, A-mab-huIFNa2-6-9 and A-mab- (huIL10)2-6-9 bound to mesothelin expressed on NCI-N87 cells.

Briefly, the buffer solution (50mM Na) was used₂CO₃/NaHCO₃(ii) a pH9.6) 2. mu.g/ml of EGFR-huFc coated ELISA plates at 4 ℃ overnight. The plates were washed 3 times with PBST (pH7.4) containing 0.05% (V/V) Tween-20 and blocked with 3% BSA in PBS for 1h, after which serial dilutions of Erb-huIFNa2-6-9 were added andincubate at 37 ℃ for 2 hours. Then 1. mu.g/ml anti-huIFN alpha biotin was added and incubated at 37 ℃ for 1 hour. Subsequently, 1: SA-HRP was diluted 1000 and incubated at 37 ℃ for 40 min. Binding was detected with (TMB, TIANGEN cat # PA 107-01; batch No. 1614) substrate and 2M H was used₂SO₄And (6) terminating. Absorbance at 450nm-650nm was measured in a Molecular Devices SpectraMax Plus-384 microplate reader. The concentration was determined using the computer program SoftMax Pro 5.4.

Mouse fibroblast L929 line or human hepatoma cell line HepG2 was infected with EGFP (enhanced green fluorescent protein) labeled Vesicular Stomatitis Virus (VSV) to examine the activity of interferon in enhancing the antiviral ability of cells. The activity of muIFNa4, muIFNb and huIFNa2 was tested separately. Briefly, cells were cultured for 8 hours in the presence of serial dilutions of the protein heterodimer of the present application, and then appropriate numbers of VSV-EGFP-infected cells were added. After 24 hours, the percentage of infected cells was determined by flow cytometry analysis and the protection rate of the protein heterodimers against viral infection was calculated. EC50 was then obtained from a dose-response curve of protection rate and protein heterodimer concentration. As shown in FIG. 13, heterodimers Erb-muIFNa4-6-9(A), Erb-muIFNb-6-9(B) and Erb-huIFNa2-6-9(C) protected cells from viral infection.

7.2 Presence and biological Activity of interleukins in protein heterodimers of the present application

The presence of huIL10 in the heterodimer Erb- (huIL10)2-6-9 was confirmed by ELISA, as shown in FIG. 12. Briefly, ELISA plates were washed with 5. mu.g/ml of buffer (50mM Na)₂CO₃/NaHCO₃(ii) a ph9.6) of anti-human IL10(BioLegend, batch No.: b179948) and at 4 ℃ overnight. The plates were washed 3 times with PBST (pH7.4) containing 0.05% (V/V) Tween-20 and blocked with 3% BSA in PBS for 1h, then a 2-fold series of Erb- (huIL10)2-6-9 diluted from 2000ng/ml was added and incubated at 37 ℃ for 2 hours. 2. mu.g/ml EGFR-Fc-biotin was then added and incubated at 37 ℃ for 1 hour. After that, 1: SA-HRP was diluted 1000 and incubated at 37 ℃ for 40 min. Binding was detected with (TMB, TIANGEN cat # PA 107-01; batch No. 1614) substrate and 2M H was used₂SO₄And (6) terminating. Absorbance at 450nm-650nm was detected in a Molecular Devices SpectraMax Plus-384 microplate reader. The concentration was determined using the computer program SoftMax Pro 5.4.

Interleukins inhibit Lipopolysaccharide (LPS) -stimulated TNF- α release from macrophages (David F. et al, 1991, Journal of Immunology, Vol.147 3815-3822). To test this activity of interleukins in the protein heterodimers of the present application, human Peripheral Blood Mononuclear Cells (PBMCs) were seeded in 96-well plates and the suspended cells were washed out after 3-4 hours. Then, Erb- (huIL10)2-6-9, Mab806- (huIL10)2-6-9 and Tma- (huIL10)2-6-9 of the present application were added at various concentrations and 2. mu.g/ml LPS was added after 2 hours for stimulation for 24 hours. Supernatants were collected and examined for TNF-. alpha.release using ELISA. ELISA was performed according to the instructions included in the TNF-. alpha.kit (eBioscience, 88-7346). Briefly, the capture antibody was diluted with coating buffer and then coated with Costar 9018ELISA plates. Then, standards and some appropriately diluted samples were added. Thereafter, the reaction was detected using a detection antibody and developed with TMB. The results are shown in fig. 14. As shown in FIG. 14A, Erb- (huIL10)2-6-9 inhibited TNF-. alpha.release in a dose-dependent manner. FIG. 14B also shows that Mab806- (huIL10)2-6-9 and Tma- (huIL10)2-6-9 of the present application were also effective in inhibiting TNF- α release in a dose-dependent manner.

Example 8: antitumor activity of protein heterodimers

8.1 antitumor Activity of Erb-Interferon heterodimers of the present application

The wild type mouse model of C57BL/6 was used to test the in vivo anti-tumor activity of Erb-muIFNa4-6-9 heterodimer. Briefly, 8 week old female C57BL/6 mice were injected subcutaneously with 7X 10⁵B16-EGFR (FIG. 15A) or 1X 10⁶MC38-EGFR (FIG. 15B) cells. After 7 days, the tumor volume was determined to be about 70mm³. Erb-muIFNa4-6-9 heterodimer or the control antibody cetuximab (erbitux, Merck) was injected intraperitoneally (i.p.). Erb-muIFNa4-6-9 heterodimer was injected at 2mg/kg and 0.5mg/kg, respectively, with a cetuximab dose of 2 mg/kg. Tumor size was measured twice weekly and tumor volume was calculated to obtain tumor growth curvesA wire. The results show in FIG. 15 that Erb-muIFNa4-6-9 heterodimer effectively reduced the tumor volume in vivo for each dose.

Similar to example 8.1, Erb- (huIL10)2-6-9 was tested for in vivo anti-tumor activity using the C57BL/6 mouse model. Briefly, 8 week old female C57BL/6 mice were injected subcutaneously with 7X 10⁵B16-EGFR cells (FIG. 16A) or 1X 10⁶MC38-EGFR cells (FIG. 16B). After 7 days, the tumor volume was determined to be about 70mm³. One intraperitoneal (intraperitoneal) injection of Erb- (huIL10)2-6-9 heterodimer or the control antibody cetuximab (erbitux, Merck). Erb- (huIL10)2-6-9Erb- (huIL10)2-6-9Erb- (huIL10)2-6-9 heterodimer was injected at two different doses (1 mg/kg and 4mg/kg, respectively), with the dose of cetuximab being 4 mg/kg. Tumor size was measured twice weekly and tumor volume was calculated to obtain tumor growth curves. The results are shown in fig. 16A and 16B.

Similarly, Balb/c mice were inoculated subcutaneously in the right flank 5X 10⁵Tubo-EGFR. Mice were treated with Erb- (huIL10)2-6-9 heterodimer i.p. injections 3 times at two different doses (1 mg/kg and 4mg/kg, respectively) on

days

7, 10, and 14. Erb- (huIL10)2-6-9 effectively reduced tumor volume in vivo in a dose-dependent manner, as shown in FIG. 16C.

8.3 antitumor Activity of other protein heterodimers of the present application

Similar to example 8.1, Erb-husIL2-6-9 was tested for in vivo anti-tumor activity using the C57BL/6 mouse model. Briefly, 8 week old female C57BL/6 mice were injected subcutaneously with 7X 10⁵B16-EGFR. After 7 days, the tumor volume was determined to be about 70mm³. Every three days, 2mg/kg of Erb-husIL2-6-9 heterodimer or PBS was injected intraperitoneally (i.p.) for five doses. Tumor size was measured twice weekly and tumor volume was calculated to obtain tumor growth curves. The results are shown in FIG. 17, where it can be seen that Erb-husIL2-6-9 heterodimer effectively reduced tumor volume in vivo.

Tma- (huIL10)2-6-9 heterodimer was also tested using the C57BL/6 mouse modelThe in vivo antitumor activity of (1). Briefly, 8 week old female C57BL/6 mice were injected subcutaneously with 5X 10⁵B16-Her2 (FIG. 18A) or 5X 10⁵MC38-Her2 cells (FIG. 18B). After 7 days, the tumor volume was determined to be about 70mm³. Tma b- (huIL10)2-6-9 heterodimer protein or PBS were injected intraperitoneally (ip) at different doses (8 mg/kg, 4mg/kg, 2mg/kg, and 1mg/kg, respectively) on

days

7, 10, and 14. Tumor size was measured twice weekly and tumor volume was calculated to obtain tumor growth curves. The results show in FIGS. 18A and 18B that Tma (huIL10)2-6-9 heterodimer effectively reduced tumor volume in vivo for each dose administered.

Similarly, the C-mab- (huIL10)2-6-9, 28H1- (huIL10)2-6-9, and 28H1-huIFNa2-6-9 heterodimers were also tested for anti-tumor activity in MC38-GPC3, MC38-FAP, B16-GPC3, and B16-FAP isogenic tumor models, and significant anti-tumor effects were observed.

Specifically, 28H1-huIFNa2-6-9 was tested for anti-tumor activity in a pancreatic cancer model (in vitro micro-organ culture system), and inhibition of tumor growth was observed.

The B16-FAP syngeneic tumor model was also used to test the in vivo anti-tumor activity of 28H1- (huIL10)2-6-9 heterodimer. Briefly, 8 week old female C57BL/6 mice were injected subcutaneously with 7X 10⁵B16-FAP-5 cells. After 7 days, the tumor volume was measured to be about 70-100mm³. 28H1- (huIL10)2-6-9 heterodimer protein, 28H1 antibody control, or IgG1 isotype control were injected intraperitoneally (ip) at 4mg/kg on

days

7, 10, and 13. Tumor size was measured every five days and tumor volume was calculated to obtain tumor growth curves. The results are shown in fig. 24, where it can be seen that 28H1- (huIL10)2-6-9 heterodimer effectively reduced tumor volume in vivo and was more effective than IgG1 isotype control or 28H1 antibody control.

In addition, Erb- (huIL10)2-6-9, Erb-muIFNa4-6-9, C-mab- (huIL10)2-6-9, 28H1- (huIL10)2-6-9, 28H1-huIFNa2-6-9, and E-mab- (huIL10)2-6-9 were also tested for in vivo anti-tumor activity in the corresponding humanized PDX mouse model, and an in vivo anti-tumor effect was observed.

Specifically, the PDX mouse model was also used to test Erb- (huIL10)2-6-9 heterodimer antitumor activity in vivo. Briefly, 8-week-old female Hu-CD34 NSG mice were implanted with pancreatic cancer A15668P 4 PDX tumor cells. When the measured tumor volume is 100mm³On the left and right, Erb- (huIL10)2-6-9 heterodimer protein (0.2mpk) or isotype control (batch No. 20170816, Crownbio, 1mpk) was injected intraperitoneally (i.p.). Day 0 (date of first administration), day 3, day 6, day 9, day 12 and day 15. Tumor size was measured every two days and tumor volume was calculated to obtain tumor growth curves. The results are shown in fig. 25, where it can be seen that Erb- (huIL10)2-6-9 heterodimer effectively reduced tumor volume in vivo in the PDX mouse model.

Example 9: targeted behavior of protein heterodimers in vivo

Similar to the procedure shown in example 8.1, the C57 BL/6B 16-EGFR mouse model was used to examine the in vivo distribution of Erb- (huIL10) 2-6-9. Briefly, 8 week old female C57BL/6 mice were injected subcutaneously with 7X 10⁵B16-EGFR-SIY cells. After 7 days, the tumor volume was determined to be about 45mm³. Erb- (huIL10)2-6-9 heterodimer or control heterodimer Tmb- (huIL10)2-6-9 labeled with Alexa Fluor 750(AF750) was injected intraperitoneally (i.p). AF750 immunofluorescence signals were screened either in vivo using IVIS spectral in vivo imaging system (Perkin Elmer) or in vitro after tumor removal 24 hours post injection. The results (as shown in FIG. 19) demonstrate that Erb- (huIL10)2-6-9 concentrations are much higher than Tma- (huIL10)2-6-9 concentrations in EGFR-positive tumors. Thus, the protein heterodimers of the present application can effectively target a target tissue (e.g., a tumor) in vivo.

Example 10 ADCC Effect of protein heterodimers

Antibody-dependent cell-mediated cytotoxicity (ADCC) was also tested against the protein heterodimers of the present application. LDH release was used to test the ADCC effect of protein heterodimers of the present application (e.g., Erb-huIFNa2-6-9 and Erb- (huIL10) 2-6-9). Briefly, PBMCs were obtained from heparinized peripheral blood samples of healthy donors by Ficoll-Hypaque density gradient centrifugation, then incubated at 37 ℃ in 1 x 10E7 cells/petri dish with 1640 medium containing 30ng/ml IL-2 and 10% FBSCulturing for 24 h. PBMC cells and a431 cells were seeded in 96-well plates at a density of 2.25 x 10⁵Pore and 1.5 x 10⁴Per well, and add 1640 medium containing 15ng/ml IL-2 and 2% FBS. Erbitux, Erb-huIFNa2-6-9 and Erb- (huIL10)2-6-9 were diluted 5-fold starting at 9nM (final concentration of 3nM) to obtain 8 different doses, which were then added to 96-well plates. After 5 hours, LDH was detected in each well.

As shown in figure 20, the protein heterodimer showed ADCC activity comparable to the control erbitux, although slightly lower, indicating that the modification in the Fc region (i.e. the first and/or second modification of the protein heterodimer of the present application) did not disrupt ADCC activity.
